Feature Request: Additional Data like URL of a song

Would it be possible to add a Link to iReal Songs? e.g. a Link to a youtube Video where the song is performed or that was a template for writing the chords in iReal Pro. Sometimes that would help to recognize it better.
Also interesting would be an option to have some additional info like: Improvising concept e.g. someone could add to the song "My Funny Valentine" that it makes sense to improvise in melodic moll at the beginning etc.

So basically an option of adding an information page to a song would be great.
